Control panel for a furniture Control and The electrically adjustable ^¬ res furniture

The invention relates to a control panel for a furniture control for controlling an electrically adjustable furniture and an electrically adjustable furniture with such a control panel. Nowadays adjustable furniture, in particular electrically adjustable furniture are widely used. For example, Ti ^¬ cal, especially work desks or desks, ^{¬ offered} , which are electrically adjustable in their height or tilt of the table top. Other examples of known electrically adjustable furniture beds, as hospital beds ^¬ in which an inclination of the lying surface is adjustable, and chairs or armchairs, in which the slope of a Rü ^¬ backrest can be adjusted electrically. In addition to corresponding adjustment motors and a controller for controlling these motors controls or controls are provided with which a user of the furniture can make the desired settings. Such a control unit can be integrated into a control or else corresponds arranged removed from the controller so that the Be ^¬ serving part can be placed individually.

In conventional control units, the design of a user interface for the user is usually fixed, for example, by the fixed positioning of Tasterele ^¬ elements in the control panel, whereby, inter alia, a board layout of a board on which the button elements are attached, and the design of a housing of the control panel firmly are predetermined. If an individual or deviating design of the operating part is desired by a customer, a new circuit board must therefore be designed and manufactured and, for example, a new injection mold be provided for the housing. This increases the production costs for individually adapted control panels.

A problem to be solved is to provide a flexible Kon ^¬ concept for the design of a control panel for a Möbelsteu- augmentation, which allows in particular an individually fitted ^¬ operation of the operation part.

This object is achieved by the subject matter of the independent Pa ^¬ tentansprüche. Embodiments and further developments are the subject of the subclaims.

In one embodiment, a control panel for a furniture control for controlling an electrically adjustable furniture is provided. The control unit includes a sheet sensor module having a plurality of positions arranged on the sensor module proximity-sensitive sensor surfaces, an operator panel for covering the plurality of sensor surfaces, wherein one set is labeled buttons on the operation panel, and a STEU ^¬ ermodul, which is set up on the basis of sensor pulses emanating from the sensor surfaces to detect an actuation of one of the buttons, and to generate a control signal for the furniture control on the basis of a detected operation. The control panel further includes a housing in which the sensor module and the control module are arranged, and wherein the control panel forms a lid of the housing. For example, the sensor module between the control panel and the control module is arranged. In this case, the operating panel is preferably arranged directly above the sensor module, in particular in direct contact with the sensor module. The marked on the control panel buttons are visible in particular on the outside of the housing and provided, for example, on the side of the control panel, which faces away from the Sensormo ^¬ module. The control module has in various embodiments, to a microcontroller, which is electrically coupled to the sensor surfaces, in order to evaluate the sensor signals corresponding to the attached ^¬ connected sensor surfaces. A user of the control unit comes with an operation of one of the buttons only in contact with the control panel, but not with the sensor module or the Sensorflä ^¬ chen, which are covered by the control panel. A detection of an actuation of one of the buttons takes place on the principle of the detection of a proximity of a body part, in particular a finger, to one or more of the sensor surfaces. The sensors formed by the sensor surfaces are based for example on resistive measurement, surface acoustic wave measurement, capacitive measurement or the like. In various embodiments, the sensor surfaces each have a capacitive sensor. In particular, it is possible that the sensor surfaces are formed by a multiplicity of electrodes which are arranged in grid form on the sensor module. Here, preferably each Sen ^¬ sorfläche is each formed by an electrode. The sensor ^¬ surface or electrodes are thus, for example adjacent to each other disposed on the sensor module. The control module or a microcontroller of the STEU ^¬ ermoduls, for example, adapted to detect a change of the capacitance value at each of the sensor surfaces relationship ^¬ example electrodes when a finger of a user-dec moves above the operating panel or the Sensormo ^¬ dul. In this case, for example, the capacitance value of each of the electrodes or sensor surfaces is measured, and a position of the finger is determined from the measured capacitances. For determining the position in this case not only a capacitance value of a sensor surface may be used, but also a plurality of adjacent particular capacitance values Sen ^¬ sorflächen which lie below one of the buttons on the control panel.

According to an embodiment, each button of the set of buttons covers a group of sensor surfaces of the plurality of sensor surfaces. Such a group includes, for example one or more sensor surfaces which are playing covers at ^¬ from the associated button. Such an overlap of the sensor surfaces of such a group can take place completely or at least partially. The degree of coverage of a sensor surface of such a group by the overlying button determined at ^¬ game as the capacitance value to be achieved completely or approximately with the other capacitance values of the group to detect an actuation of the associated button.

In one embodiment, the control module is configured to detect an actuation of one of the buttons based on detection parameters that determine a relationship between each of the buttons and an associated group of sensor surfaces whose sensor signals are for detection. on pressing this button. Such detection parameters are evaluated in various embodiments by a microcontroller of the control module. The De ^¬ tektionsparameter include, for example, the information, which are associated with the sensor surfaces of a certain button, and how the coverage ratios relationship ^¬ as capacity ratios of these sensor surfaces relative to the associated button are. Such detection parameters are stored, for example, in a parameter memory, which may be integrated in the microcontroller, or provided separately from the microcontroller on the control module. An actual operation program of the microcontroller, which includes a detection algorithm, which uses the stored ge ^¬ detection parameters to evaluate the sensor signals can be maintained in a separate program memory. Such a program may for example be integrated in a firmware of the control module.

The control module may also include an external interface in various embodiments, may be on the read out Detekti ^¬ onsparameter respectively transmitted to the control module. Such an interface can be realized for example by a serial interface, a USB interface or a wireless interface. With such an interface, it is a user relationship ^¬ example allows a furniture manufacturer, depending on a design of the control panel, in particular the positioning of the buttons on the control panel, apply a customized and adapted parameterization of the detection parameters men. By separating the operating program and detection parameters, it is possible to prevent the control module or the operating unit from becoming unusable even if the parameterization is erroneous. .

Furthermore, it is possible that the control plate has a SpeI ^¬ cher for storing the detection parameters wherein the control module is adapted to read out the detection parameters from the memory. Accordingly, may be provided directly on the control panel to ^¬, which are matched to the positioning of the buttons on the control panel Detekti- onsparameter. Thus, the implementation ^¬ effort when assembling the control panel can be further reduced.

According to one embodiment, the marking comprises the

Buttons on the control panel at least one of fol ^¬ ing: A printing of the control panel, a printed Fo ^¬ lie, which is applied to the control panel, a structured surface of the control panel. Accordingly, the control panel, which is made for example of plastic, printed directly, with a Markie ^¬ tion of the buttons is done by the printing. Alternatively or additionally, a correspondingly printed film can be applied to the control panel. Furthermore, it is possible for the buttons to be marked by structuring, in particular mechanical structuring of the surface of the operating ^panel . According to a further embodiment, the sensor module and the control panel are movably mounted in the housing, wherein the control panel has at least one electromechanical switching element which can be actuated by a movement of the sensor module. In particular, the sensor module and the control panel are provided for axial movement perpendicular or substantially perpendicular to the surface of the control panel. A location ^¬ tion, for example, with a bias by one or more springs. When pressing down the control panel or the sensor module can thus be closed in the electromechanical switching element, an electrical contact. The generation of the actuation signal for the furniture ^¬ control can be made dependent in this case both of the operation of one of the buttons and the simultaneous operation of the electromechanical switching element.

In a further embodiment, the control unit further comprises a vibration motor, wherein the control module is arranged to control the vibration motor at a detected actuation. Thus can be given to the user of the operating unit haptic feedback, which signals a erfolgrei ^¬ che pressing the button. This is in particular possible with ^¬ sondere keypads in which the control plate is fixedly applied to the housing.

According to a further embodiment, the control module has a plug-in connection, into which a touch module can be inserted, which has at least one electromechanical button. Thus, in addition to the buttons on the control panel, which are evaluated via the sensor module, also other switches are provided which allow an individual adjustment of the control panel. The control module can also have several plug-in connections, whereby the Variation- tion possibilities for attachable button modules are increased. The operating plate preferably also covers the keys ^¬ module and has, for example openings or flexible Be ^¬ rich, by which the electromechanical button of Tas ^¬ tenmoduls operable. In various embodiments, the key module can have further plug connections which make it possible to connect further key modules. ₀

In other embodiments on the control module, a display element, for example a multi-digit segment display ^¬ be provided so that the user with information, for example on an operating state of the CEE belsteuerung can be provided. Accordingly, for example, has the sensor module a entspre ^¬ sponding recess, through which the display device extends therethrough. Likewise, a recess or a transparent region can be provided in the control panel, so that a visibility of the display device is ensured from the outside.

In the embodiments described, an arbitrary number of sensor surfaces, which is limited only by the processing capability of the microcontroller, can be provided on the sensor module without incurring additional costs for keys or assembly of the control module. For example, which of these ^anticipated surfaces are used for which functions is only dependent on the parameterization of the microcontroller and can be determined by a corresponding design of the microcontroller

Surface of the control panel, in particular the marking of the buttons are displayed. Since combinations of a plurality of sensor surfaces can also be detected during the detection, almost any position of such a button can be detected if the sensor surfaces are arranged close to one another. Accordingly, one is not bound in the design of the surface of the control panel to arrange a button directly above a sensor surface. This he ^¬ enables to distribute the key arrangement including features on the entire surface of the operating panel individually or move. According to one embodiment, an electrically adjustable furniture is provided with a furniture control and a control panel connected to the furniture control according to one of the embodiments described above. For example, such an electrically adjustable furniture is an electrically adjustable table, an electrically adjustable armchair or an electrically adjustable bed.

The housing of the control unit can be fastened with a holder on the electrically adjustable furniture, for example with a sliding device below a table top, so that the control panel can be pulled out under the table top if necessary. Furthermore, the housing may also be provided for installation in the electrically adjustable furniture. For example, a recess is provided in a table top or in a back of a chair, in which the housing of the control panel is used.

The invention is described in several Ausführungsbei ^¬ play reference to the figures explained in more detail. Functional rela ^¬ hung as effective like elements bear like reference characters here.

FIG. 4 shows a further embodiment of a control unit, Figure 5 shows another embodiment of a control panel, and

Figure 6 shows several embodiments of a control module with

Key modules.

Figure 1 shows an embodiment of a control panel 1 for a furniture control for controlling an electrically adjustable furniture, with an exploded view is selected for a better overview. The control unit 1 comprises a Be ^¬ dienplatte 10, a sensor module 20 and a control module 30, which are together in a housing 40 of the control unit 1 is set ^¬ . The control panel 10 further forms a lid of the housing 40.

On the control panel 10 four buttons 11, 12, 13, 14 are marked here, wherein the number of buttons is chosen only by way of example and can be varied as desired. The sensor module 20 is designed flat and has a plurality, in this case twenty, of on the sensor module 20 at ^¬ parent approximately sensitive sensor surfaces 20a to 20t on. The number of sensor surfaces is again chosen only by way of example and can be varied. The sensor surfaces 20a to 20t are each formed by an electrode, for example, and form a grid-shaped arrangement on the sensor module 20. Each of the electrodes may be formed by one or more layers of electrode material. The switching ^¬ surfaces 20a to 20t show, in particular to the electrodes a capacitive sensor.

The control module 30 includes a microcontroller 31, wel ^¬ cher is furnished for evaluating sensor signals output from the sensor surfaces 20a to 20t become. The markings of the buttons 11, 12, 13, 14 each cover one or more of the sensor surfaces 20a to 20t, so that for each of the buttons 11, 12, 13, 14 an associated group of sensor surfaces is determined, which by the respective button or partially covered over ^¬ . By evaluation of sensor signals, which are output from the sensor surfaces 20a-20t, thus a pressing one of the buttons 11, 12, 13, 14 detek- advantage be, wherein in case of a detected operating an actuating signal for a not shown here furniture ^¬ control can be generated. The furniture control, for example, implement the operation signal into a movement of elekt ^{¬-adjustable} furniture. For example, if a capacitive detection principle is used, absolute or relative capacitance values amendments ^¬ conclusions of the capacitance value of the sensor surfaces can be evaluated to detect the approach about a user's finger which actuates a button. For example, when a finger of one of the electrodes passes beziehungswei ^¬ se sensor areas, a small capacitance between the sensor surface and the finger, which results in a corresponding sensor signal, which is output from the Sen ^¬ sorfläche to the control module forms.

Figure 2 shows an embodiment of an operating plate 10 with a sensor module 20, which may alternatively be used in the execution ^¬ form of the control unit 1 of FIG. 1 The control panel 10 has the buttons 11, 12, 13, 14, which are marked with the numbers 1 to 4. Further, on the control panel 10 buttons 15, characterized by an arrow up, 16, characterized by an arrow down, and 17, characterized by the letter S, marked. Furthermore, an opening or a transparent area is provided in the operating panel 10, through which a display device or a display is visible. Accordingly, the sensor module 20 in addition to the previously described buttons 20a to 20t has a recess through which the display device can protrude through.

To clarify the principle of detecting an actuation of one of the buttons, the positions of the buttons on the overlying control panel 10 are marked on the sensor module 20.

Accordingly, a group of sensor surfaces belonging to the button 11 comprises the sensor surfaces 20a, 20b, 20c and 20d. Further groups, which belong to the other buttons 12 to 17, arise according to the same principle from the representation of the sensor module 20 through the sensor surfaces, which are at least partially covered by the corresponding button ^¬ .

The degree of overlap of one of the sensor surfaces also determines the capacitance ^value , or the capacitance ^{value range} , which, when actuated, lies above it

Button is reached. Accordingly, detection parameters can be defined which determine a relationship between a button and the associated group of sensor surfaces whose sensor signals serve to detect the actuation of this button surface. Such detection ^parameters can be defined for each button from the set of buttons 11 to 17. In particular, these detection parameters are available to the control module 30 or the microcontroller 31 for the evaluation of the sensor signals, which from the buttons 20a to 20t are available.

In various embodiments, the detection parameters can be stored in a parameter memory on the control module 30 or in the microcontroller 31. Wei ^¬ terhin it is possible that directly in or on the control panel 10 such a parameter memory is provided, which has the corresponding information and parameters on the marked buttons 11 to 17. The parameters of the parameter memory of the control panel 10 can be made available in the control module 30 by electrical contacting or alternately ^¬ tive by reading a transponder, for example according to the RFID principle.

Furthermore, it is possible that an interface for programming and / or parameterization is provided on the control module 30, which allows, for example, a transmission of detection parameters from a computer. For example, a parameterization software is provided on the computer, via which corresponding detection parameters are generated on the basis of defined button positions. As an interface any known interface of ^¬ len such as USB, infrared, Bluetooth or others can use the advertising.

An actual operation program of the microcontroller 31, which includes a detection algorithm, which uses the stored ge ^¬ detection parameters to evaluate the sensor signals can be maintained in a separate program memory. Such a program may for example be integrated in a firmware of the control module. A marking of the buttons 11 to 17 on the control panel 10, for example, by direct printing of the control panel, which is made for example of plastic, done. Alternatively or additionally, it is also possible to use a printed film on which the markings of the buttons are provided, and which is glued or otherwise applied to the surface of the operating panel 10. Furthermore, it is also possible to mark the

Buttons by a design of the surface structure of the control panel 10 to achieve, for example, by milling or milling the markers or buttons.

The design of the buttons, in particular the positioning of the buttons on the control panel 10 can be carried out variably according to the described principle and in particular is not bound to the position of the underlying sensor surfaces. This makes it possible that a user or a manufacturer of the control panel or the electrically adjustable furniture, with which the control panel is used, can choose an individually designed user interface.

Figure 3B shows a control panel 10 with nine buttons 11 to 19, wherein in addition to the previously described buttons 11 to 17 two further arrows marked with buttons 18 and 19 are provided for further control operations. A marker of the buttons 11 to 19 on the control plate 10 is formed by the labeling with jewei ^¬ time symbols. The embodiment of the operating panel 10 in FIG. 3B also has an area in which a display device can be provided.

The actuation of the electromechanical switching elements 35, 36 is preferably haptically and / or acoustically noticeable by the user, for example by clicking on the actuation of the switching element. This increases the user-friendliness and operating safety for a user. In an alternative or additional embodiment, the panel 1 may also comprise a vibration motor which is for example in the area of the operating plate 10 Bezie ^¬ hung example of the sensor module 20 is mounted. In a detected actuation of one of the buttons, with or without actuation of an electromechanical switch, which is not absolutely necessary in such an embodiment, the vibration motor can be activated to give the user turn a haptic feedback on the operation done.
